可以检测图像中圆和直线的信息，有利于初学者使用学习。-Edge detection has played an important role in the field of computer vision. A parametric edge detection method based on recursive mean-separate image decomposition is introduced. A method for automatic parameter selection

demo中包括了目前常用的边缘检测算子，并添加了frei-chen、kirsch、drecedge、prewittcompass等边缘检测function函数。此外，实现了Ruzon罗盘算则的matlab编程，可以对灰度图像加以处理，实现边缘检测。-demo includes the most commonly used edge detection operator, and added frei-chen, kirsch, drecedge functions such as edge de

demo中基本上整理了目前常用的所有边缘检测算子，并添加了自定义的frei-chen、kirsch、direcedge、PrewittCompass、RobinsonCompass边缘检测算子function函数。此外，还有Ruzon罗盘算子的matlab实现程序，能对灰度图像的边缘加以检测。-demo, basically compiled all the commonly used edge detection operator, and add a custom frei-chen, ki

为了在实际应用中能够选择最佳的边缘检测方法，采用Matlab语言鳊程，将若干常用的边缘检测方法应用于花瓶边缘检测仿真实验．包括微分算子法(Robert算亍、Sobel算予、Prewitt算子和Kirseh算子)、高斯一拉普拉斯算子法、坎尼算子法、零交叉法和Frei—chen边缘检测法等,并进行了对比分析。-In practice, in order to be able to the best edge detection method using Matlab language bream
